  • Q:

    Ionization energy increases with decreasing atomic radius because

     

    A

    the nuclear radius increases, pulling the electrons more strongly because of the proximity and increasing the energy required to ionize the atom.

    B

    decreasing atomic radius requires higher energy orbitals which command a higher energy input during ionization.

    C

    the number of electrons in atoms increases, meaning stronger repulsive forces against energy inputted to ionize the atoms.

    D

    the electrons are closer to the strong attractive forces of the nucleus and require a higher energy input to be removed.
